用had
這是賓語從句的語法問題,主句為Do you know過去式,從句用過去范圍內(nèi)的某種時態(tài),所以用if he had finished his work（過去完成時）
注：原題有誤,應(yīng)該是finished,had+動詞過去分詞 是過去完成時的結(jié)構(gòu)
"Did you know if he has\had finish his work?"一句中應(yīng)是if he has還是had?
"Did you know if he has\had finish his work?"一句中應(yīng)是if he has還是had?
Did you know if he has finished his work?
注意：這里if是“是否”的意思
Did you know if he has finished his work?
注意：這里if是“是否”的意思
